Machine for Crushing Feathers and for Pula verizing, of which the following is a specification.

Myinvention relates to machines for crushing and tearing feathers and for pulverizing; and the objects ofmy improvements are, first, to render fluify and downy those kinds of feathers which heretofore have been regarddown from the quills of large feathers and to tear the vanes from the quills and so crush and crimp them as to render them soft and fluffy; third,t0 thoroughly mix different kinds and qualities of feathers together; fourth, the

adjustment of the machine for any desired fineness of the product; fifth, to produce a machine of the class named that is not liableto injury by scraps of iron, old shoes, &c., but will stop before breaking; sixth, dura bility; seventh, saving of power in producing the desired results; eighth, saving of floorspace; ninth, rapidity of production, and,

11 is the key for securing radial arms 3 to shaft 9.

12 represents bolts which pass through perforations in the outer ends of the stationary arms 2, the blocks 5, and the lugs on the frame.

The casing 1. is separable into halves at the bearings of the shaft 9 and bolted through the flange at the parting of the h'alves. At

-intervals about the periphery of the casing it is pierced by rows of slots, through which the stationary radialarms 2 are inserted. 'The stationary radial arms 2 are solid bars of the best tool-steel of rectangular cross-section, extend inward nearly to the shaft, and are firmly held in place by the sides of the slots through the casing and by bolts 12 and. blocks 5. The revoluble radial arms 3 are also made of solid bars of best tool-steel, each bar extending across the machine and being pierced at its middle forthe shaft 9 and splinedfor the key 11. These bars are of rectangular crosssection and have their edges tapered from the middle toward each end. The ends are truncated and extended almost to the toothed These arms 3 are not arranged on the shaft in straight lines, but spirally, so as to produce the efiectof a screw conveyor and avoid shocks in. the machine. The toothed lining 4 is made in sectionsand screwed firmly to the periphery of the casing, and the teeth slant opposite to the direction of motion of the revolving arms 3. The opening which communicates with the conveyer 7 extends half across the periphery of the cylindrical casing and is controlled by the sliding shutter 10. The feed-opening 8 is in the side of the casing and is placed on the side opposite the outlet, so that the material must pass across and receive the action of the machine before escaping to the conveyer.

The working of the machine will now be fully understood. The raw material is introduced at 8 and is drawn in by the centrifugal action of the revolving arms 3. It is caught by arms 3 and beaten between arms 2. The action of the square edges of the arms 2 and 3 is not to cut-,but to tear and crimp. As the action is continued the spirally-arranged arms 3 convey the material across.

At the same time the centrifugal action of arms 3 forces it against the toothed lining 4, where the truncated ends of arms 3 give it a thorough crushing and rubbing. until it finally escapes through the outlet. If the product is to be very fine, the shutter 10 is pushed over so as to almost close the outlet, thus requiring the material to traverse the entire machine. When tobacco or other material is to be pulverized, a perforated or wire-cloth shutter of the required fineness is used to cover the entire outlet.

Having now described myimprovement, so that any one skilled in the art pertaining thereto may make and operate it, I desire not to be limited to the particular construction shown and described, and I do not desire to claim all the parts mentioned, broadly; but

What I do claim as my invention, and decombination of a separable cylindrical casing, transverse rows of rectangular perforations through the periphery of said casing, bars of rectangular cross-section, having one end.

pierced, passing through the said rectangular perforations in the casing, blocks of yielding material perforated and placed between the perforated outer'ends of aforesaid bars, a bolt passing through the perforations of each row of blocks and bars, a sectional lining on the periphery of the casing consisting of blunt teeth cast integral with curved plates, a shaft passing axially through the casing and revoluble in boxes on the sides of the casing, a row of diametral bars keyed on said shaft and so spaced as to pass between the stationary bars and so disposed as to form a spiral, substantially as and for the purposes specified.

2. In a feather crusher and pulverizer, the

combination of a cylindrical casing 1, trans verse rows of arms 2 of rectangular cross-section, rigidly fastened in the periphery of said casing, a revoluble shaft 9 passing axially through said casing,'a spiral row of tapered diametral arms 3 rigidly fastened to said revoluble shaft, a toothed peripheral lining 4 with teeth slanting opposite to the direction of motion of the revolving arms 3, an inlet-opening 8 in one side of the casing 1, and an outletopening in the periphery of the casing 1 on the side of said casing opposite to that having the inlet-opening, and a sliding shutter 10 to control the outlet-opening, substantially asand for the-purpose specified.
